What event sparked the beginning of the American Revolutionary War?

The Battles of Lexington and Concord mark the beginning of the American Revolutionary War because they were the first military engagements between the American colonists and British troops. On April 19, 1775, these battles took place when British troops were sent to confiscate colonial weapons and arrest revolutionaries. The confrontations effectively ignited the conflict that had been brewing due to rising tensions over British taxation and governance without representation.

This pivotal moment catalyzed the revolutionary movement throughout the colonies, leading to a widespread enlistment in the Continental Army and rallying support for independence. The significance of Lexington and Concord lies in their demonstration of colonial resolve and willingness to stand armed against British authority, marking a clear transition from political dissent to armed rebellion.
